The Employee will forfeit the unvested Units to the Reacquiring Company without receiving any consideration therefor.

(c) If the Employee delivers to the Reacquiring Company a certificate which represents vested Units as well as forfeited Units, the Reacquiring Company will, or will arrange for the Partnership to, send promptly to the Employee a certificate representing the vested Units. The Employee will reimburse each of the Reacquiring Company and the Partnership, if not the Reacquiring Company, for their respective expenses (including reasonable attorneys' fees) incurred in connection with any reasonable steps they may 9 take to obtain the repayment of distributions referred to in paragraph (b) of this Section 4, and, if the certificates representing forfeited Units are not duly delivered, to obtain the certificates from the Employee or to cancel certificates not duly delivered. 5.

If the Partnership is successful with respect to a part but not all of such a suit or proceeding, such costs and expenses shall be fairly allocated, and the Employee will pay only the portion allocated to such part as to which the Partnership is successful. Similarly, if the Employee is successful in any 11 suit or proceeding instituted by the Employee to enforce any of the provisions of this Agreement or on account of any damages sustained by the Employee by reason of the violation by the Partnership of any of the terms and conditions of this Agreement to be performed by the Partnership, the Partnership will pay to the Employee all costs and expenses (including reasonable attorneys' fees) reasonably incurred by the Employee.

If the Employee does not promptly pay to the Partnership the entire amount of such withholding tax or charge in accordance with such notice, the Partnership may withhold the remaining amount thereof from any amount otherwise due the Employee from the Partnership. 13.
